### 7.1.2 Precedence

Except where the specification for a particular routing protocol specifies otherwise, a router SHOULD set the IP Precedence value for IP datagrams carrying routing traffic it originates to 6 (INTERNETWORK CONTROL).

DISCUSSION

  Routing traffic with VERY FEW exceptions should be the highest precedence traffic on any network. If a system's routing traffic can't get through, chances are nothing else will.
